Class D3 Amplifier (Direct Energy HD Amplifier)
With the Class D3 (Direct Energy High fidelity class D) Amplifier, the SC-LX801 is ready to meet the needs of the latest HD content. With our MOSFET, the Direct Power FET, this simple, high powered solution is provided to fully meet today’s AV entertainment standards. The custom bypass capacitors further enhance the advantages of the Class D3 amplifier, producing powerful bass while also delivering subtle details.
High-Power Simultaneous Multi-Channel Drive
With Class AB amplifiers, driving all channels at full power is only possible for a short time, at around 300 W to 400 W power output. The SC-LX801’s Class D3 Amplifier has the ability to simultaneously drive 9-channels at 810 W (SC-LX901) power output, while managing to deliver dynamic content, more efficiently.
The Direct Power FET is directly connected to the print circuit board without any additional wiring. This simple structure maximizes audio performance by reduced noise and improved switching, offering a quick-responding sound, perfect for digital content playback.
The Class D3 Amplifier has been designed with a simple structure to take a straight and short signal path, resulting in improved sound quality.
Improved Circuit Design
The SC-LX801 is equipped with dedicated ICs on the circuit board, all in the pursuit of reproducing a clean, clear sound. The operational amplifier IC for processing small signal is set apart from the amplifying section to prevent mutual interference. This allows clear signal to be transmitted to the Direct Power FET.
Low Heat Generation
The simple form of the Direct Power FET has the advantage of improved thermal characteristics. In addition to the upper-side heat dissipation from the heat sink, the circuit board’s heat radiation feature is also utilized for downward heat dissipation, providing efficient cooling for a superior performance.
Separate Design for Analog Small Signal
Dedicated ICs are lavishly used on the circuit in pursuit of ideal sound. The Op-amp IC for processing small signal is set apart from the amplifying section to prevent mutual interference. This allows clear signal to be transmitted to the Direct Power FET. Additionally, the Rubycon chip film capacitor MU 25p further reduces the influence of residue noise from the high power section.
ESS SABRE32 Ultra DAC
The highly acclaimed 192 kHz/32-bit ESS SABRE32 Ultra DAC (ES9016S) is adopted to deliver exceptional sound, with ultra-low distortion and high signal-to-noise ratio. It offers jitter-free performance for an astounding audio reproduction with rich deep bass, maximizing the full potential of Pioneer’s Class D3 amplifiers.
